6 Claims. (Cl. 20-53) This invention has to do with windows of the typein which the sash is pivotally mounted in a frame and is sealed in itsclosed condition by a continuous sealing gasket located in the spacebetween the outer periphery of the sash and the inner periphery of theframe.

It is a general object of the invention to provide in a window of thetype described a supporting means between the lower rail of the sash andthe bottom rail of the frame which is laterally spaced from the bottomconnecting pivot and which in the closed position of the sash willprovide a support for the portion of the same which is remote from thepivotal connection and relieve the strain on the latter, therebypreventing sag of the sash while it is closed.

It is a further object of the invention to provide a window having arectangular sash mounted within a surrounding frame on verticallyaligned pivots and having a compressible sealing strip around theperiphery of the sash in the space between the confronting surfaces ofthe sash and the frame wherein a supporting block is provided on thebottom face of the lower rail of the sash which is in laterally spacedrelation relative to the pivot and which is adapted to engage upwardlyfacing portions of the lower rail of the frame and thereby support thesash in proper squared up position within the frame while relieving thesash of any tendency to sag when in the closed position.

It is a further object of the invention to provide in a window of thetype which comprises a rectangular sash mounted on vertically alignedpivots in a surrounding rectangular frame with the outwardly facingperipheral edge of the sash spaced from the inwardly facing con frontingedge of the frame by a compressible sealing gasket and cooperating blockmembers of relatively noncompressible material arranged on theconfronting faces of the bottom rail of the sash and the bottom rail ofthe frame in laterally spaced relation to the lower pivot and alignedfor engagement with each other to hold the sash in non-sagging relationwithin the frame when the sash is in the closed position.

These and other objects and advantages of the invention will be apparentfrom a consideration of the window construction which is shown by way ofillustration in the accompanying drawings wherein:

Figure l is a perspective view of a window constructed in accordancewith the invention, the sash being shown in open or angular relationrelative to the frame;

Figure 2 is a partial elevation, to an enlarged scale, of the lowerportion of the window with the sash in closed position relative to theframe;

Figure 3 is a cross section, on the line indicated at 3-3 in Figure 2,to a still larger scale;

Figure 4 is a cross section taken on the line indicated at 4-4 in Figure2, to an enlarged scale;

Figure 5 is a perspective view of the supporting block member which isadapted to be attached to the sash; and

Figure 6 is a perspective view of a portion of the bottom rail of theframe showing the filler block carried 2 thereby in proper position formounting within the drainage gutter in the frame member.

Referring to the drawings, the window includes an outer stationary frame10 of generally rectangular form, which frame is adapted to be anchoredand sealed in any suitable manner in an opening in the wall of abuilding. The frame 10 surrounds and fits closely about a glazed sash 11with the same general rectangular form. The rail members 12 of the frame10 and the rail members 13 of the sash 11 are both preferablyconstructed of extruded aluminum but either or both may be constructedof any other suitable material.

The sash 11 is pivotally connected, preferably midway between the sideedges, to the frame 10, the pivotal connection being effected by alignedtop and bottom pivot pins 14 and 15. The sash 11 is provided about itsouter periphery with a pair of laterally spaced, continuous outwardlyopening grooves or recesses 16 (Figures 3 and 4), preferably ofgenerally rectangular cross section, in each of which a continuoussealing member 17 is partially housed. The grooves or recesses 16 openoutwardly of the edge face 18 of the sash rails 13 in confrontingrelation with the inwardly facing periphery 19 of the frame 10. Therecesses 16 are located near the outer edges of the sash rails 13 and onopposite sides of the supporting pins 14 and 15 which are located in thecenter intermediate the side edges of the same.

The pivot pins 14 and manner in the sash and frame rails, being securedin a sleeve 20 which is in turn secured in the bottom sash rail 13 andprojecting into the bearing sleeve 21 in the bottom rail 12 of the frame10. The sleeves 20 and 21 have confronting flange or shoulder formations22 and 23 which project somewhat from the faces of the respective railsand form a spacer between the sash 11 and the frame 10.

The Weatherstrip or sealing member 17 is preferably of the constructionwhich is described in my copending application Serial No. 599,119, filedJuly 20, 1956, now Patent No. 2,888,721, issued June 2, 1959. It isarranged to provide a continuous seal extending between the confrontingfaces 18 and 19 of the sash 11 and the frame 10 and comprises agenerally tubular section 24 which is distortable or compressible andwhich spans the space between the sash and the frame. The tubularsection 24 projects from a holder member 25 which is seated in therecess 16.

The bottom rail of the frame 10 is provided with the usual drainagechannel 26 (Figures 3, 4, and 6) having openings 27 at longitudinallyspaced intervals which permit any moisture collecting therein to drainoff into the interior of the frame from which it is conveyed by suitablepassageways to the exterior of the building in which the frame 10 ismounted. The sash 11 is provided on the bottom face of the lower railthereof with a pair of combination spacer and supporting blocks 28. Eachblock 28 (Figure 5) is formed of a relatively hard, substantiallynon-compressible material which provides a surface having a low frictioncharacteristic, preferably nylon plastic or the like. It is relativelyshort in length with a generally rectangular cross section, the sideedge portions being beveled or rounded at 29 to give the one facethereof a somewhat convex surface. The end portions 30 of the block 28are cut away to reduce the thickness and screw receiving apertures 31are provided therein with appropriate countersinking to receiveattaching screws 32 (Figure 4) by means of which the block is attachedto the downwardly facing surface of the bottom sash rail 13. A taperedportion 30' connects each end portion 30 with the thicker intermediateportion of the block. The blocks 28 are spaced on opposite sides of thelower pivot 15 adjacent the corners of the sash l1 and are securedinter- 15 are mounted in a similar mediate the weatherstrips 17 with thecurved face of each block projecting downwardly so that it will engagewith the uppermost face of the lower rail 13 of the frame when the sash11 is closed.

In order to provide a bearing surface in the drainage channel or gutter26 for the blocks 28 when the sash is in the fully closed position,filler members or blocks 33 are provided which are apertured at 34 atopposite ends to receive suitable fastening screws 35 for attaching theblocks 33 in proper position in the drainage channel 26. The blocks 33are located in the same relation to the bottom pivot as the bearingblocks 28 and are aligned with the latter so that they provide a bridgeacross the drainage channel or gutter 26 when the sash 11 is moved intofully closed position in the plane of the frame 10, the bearing blocks28 rest on the filler blocks 33 and retain the sash 11 in squared up ornon-sagging relation within the frame 10. The filler blocks 33 arepreferably formed of aluminum or similar material. They may, however, beformed of plastic of a character similar to that employed for the blocks28.

While specific materials and particular details of construction havebeen referred to in describing the illustrated form of the invention, itwill be understood that other materials and other details ofconstruction may be resorted to within the spirit of the invention.
